Period undies that feel like undies

No nappy feel, no plastic crackle, no bulk. Our period and leakproof range is made from the same soft, breathable Micro Modal as the rest of Pure Snug, so it feels like your favourite undies, not like period protection.

Two ways to stay protected

Not everyone wants the same thing on their period, so we make two options.

Built-in absorbency. Our Period Boxer Briefs have a discreet absorbency panel sewn right in, front to back. No pad needed. They're the self-contained choice for medium to heavy periods and overnight wear, and a favourite for sleeping in.

Leakproof core plus a pad-friendly gusset. Our Leakproof styles have a full leakproof core and a floating gusset that holds a pad with wings securely in place. The leakproof core handles accidents, light spotting and minor leaks on its own. For a heavier flow, pair them with winged pads or our reusable pads below for extra absorbency and security.

These styles are also a popular choice for light bladder leaks and everyday reassurance. For heavier incontinence needs, we'd recommend pairing with a higher-absorbency pad or our reusable night pads.

Reusable pads, made to stay put

Our reusable pads and liners are 100% organic cotton on top, with high-absorbency middle layers and a leakproof PUL backing. Liners for daily freshness and spotting, day pads for light to medium flow, and night pads for heavy and overnight protection. They tuck into any floating-gusset style so they don't shift or bunch, and they come with a wet bag for when you're out. Washable, reusable, and far kinder to the planet than disposables.

PFAS-free and gentle on skin

You've probably seen the headlines about "forever chemicals" in period products. Ours are made without intentionally added PFAS, with an organic cotton top layer against your skin. Soft, breathable, and made to be trusted.

Seamless where it counts

Our Leakproof styles have the same hot-pressed waistband and hems as the rest of Pure Snug: no dig-in, no roll-down, no line printing through your clothes. The Period Boxer Briefs are built a little differently. The extra absorbency layer can't be hot-pressed, so they have a soft stitched waistband and a back seam that makes the front-to-back protection possible. Worth knowing if you plan to wear them under very tight leggings.

The range

Sizes XS to 5XL, in a 4″ boxer brief and an 8″ high-waisted biker length. For a shorter everyday cut, see our 3″ boyleg briefs and 5″ boxer briefs, or browse the full PadStay floating-gusset range. Our sizes run a little generous, so if you're between sizes, size down.

Snug Qs (the stuff everyone asks)

It depends on the style. Our Period Boxer Briefs have an absorbency panel built in, so they work on their own right up to medium and heavy days. Our Leakproof styles have a leakproof core that handles light leaks on its own, plus a floating gusset that holds a pad in place for heavier days and overnight.

Not always. The built-in Period Boxer Briefs need no pad at all. The Leakproof styles can be worn on their own for accidents, spotting and minor leaks, and take a pad when you want extra protection for a heavier flow.

Yes. The Period Boxer Briefs handle medium to heavy flow and overnight on their own. For the Leakproof styles, add one of our night pads for heavy and overnight protection.
